1. We should educate a naughty child, encourage him more and criticize him less, discover his advantages and guide him. Secondly, praise should be carried out in public as much as possible, which will greatly increase children's self-esteem, while criticism should only be known by children themselves, otherwise it will greatly weaken children's self-confidence.

2. Educate, inculcate and cultivate, and use the existing experience and knowledge to examine people and explain various phenomena, problems or behaviors for them. Its essence is to treat people with a relatively mature or rational thinking, making things close to their most fundamental existence. In this thinking, people gradually change from sensory touch to cognitive understanding, forming a relatively perfect or rational self-conscious thinking.

As the saying goes, wash your dirty linen in public.
